GEORGE sEvIoK JONES, E CHRISTCHURCH, NEW'ZEALANDV MEANS FOR CONTROLLING THE DISCHARGE on LIQUIDS FROM CONTAINERS I Application fil ed March 25,;ie27, Serial No. 178,446, and inne Zealand January as, 1927.

This invention relates to means for controlling the discharge of liquids from containers, and has particular reference to that class of container such as bottlesused for Q holding liquid perfumes or scents, medicines or other liquids, where it isnecessary or desirable that the liquids'be drawn off only in small or measured quantities.

The invention has for its'object the provision of improved means whereby the liquid is enabled to be drawn off in'pre-determined I or measured quantities and also whereby the liquid may be continued to be drawn off un til exhausted by sprinkling, thus providing I for the economical use of the liquid, said means at the same time guarding against the placing of further liquid'in the container by making the refilling of same a tedious and in most cases an unprofitableproposition; v

The invention consists in providing for the control of the discharge ofliquid from a container, by the use in the latter of a discharge passage of small capacity in relation to the capacity of the container, said passage being formed to trap air passing to the container upon the latter being inverted and discharging liquid, the trapped air forming an air lockwhich prevents liquid from escaping through the passage until such time as the air lock is destroyed.

The invention will be more particularly described with the aid of the accompanying drawing, wherein it is shown applied to the neck of a bottle adapted to hold liquid perfume or scent.

'Figures land 2 are part vertical'sections of bottles illustrating slightly different forms of the invention. 7 V i I In the forms of'the inventionillustrated in 40 these Figures the stopper comprises two plugs 1 which are permanently secured in the bottle neck 2, so as to leave between them a chamber 15 in comunication with fine holes 16, passing right through-said plugs. I The upper or outer surface of the innermost plug 1 is made concave,'while the inner or lower surface of the outer plug 1 can be either convex Figure 1, or concave Figure 2, while in each case a small ball 17 is placed in the chamber 15, for the purpose of seating nermost plug 1 when the bottle is stood upright to prevent loss of the contents thereof f by evaporation.

The ball 17 by seating over the hole 16 in over the upper end of the hole 16 in the inthe innermost plug 1 also makes it extremely difficult to refill the bottle. a V

A pin 18 with a rubber washer 19 thereon can also be'inserted in the hole'16 in the other plug 1 tofurther'guard against loss of the bottles contents by evaporation.

' Upon the inversion of a bottle or containerprovided with a'discharge passage consisting of t-heholes 16 and chamber 15"air in at-- tempting to pass to the container. is.

trapped in the chamber 15 and forms an air lock which prevents escape of the liquid contents of the-container until such time as 'j 1 the air lock is destroyed by shaking as before It is obvious that by pressing the outer mentioned.

plug a greater or less distance into the bottle neck relative to the inner plug, the width and capacity of the chamber 15 may be varied, thus varying the measured quantity cap.- itbllg of being discharged between each air- What I do claim and desire to obtainby' Letters Patent of the United States of America is:- I I I In a liquiddispensing container, means for controlling the supply of liquid from I said container, comprising upperand lower stopper members within the neck of the contamer having alined, concentric bores for the passage of the liquid, the relatively adjacent ends of the said members being of conical form, and each concave, the said ends ofthe members being relatively spaced and the adi V jacentends of the bores in the membersopen ing into the space between the members at the apexes of the said ends of the conical rec e sses of the members, and a ball valve confined in the said space between the members and freely movable over the conicalsurfaces of the ends of the members, whereby to assume a position closing the end of either bore in different positionsjiof the container, the. i

conical recesses extending to the wall of the neck of the container at their basal ends and the upper stopper member being frictional ly held within the neck of the container, and adjustable with respect to the lower stopper member to Vary the capacity of the space bet 5 tween the relatively adjacent ends of the mem- 'bers.

In testimony whereof I have signed my a name to this specification.

GEORGE SEVIGKE JONES.
